This video illustrates six different stacking modes of the Advanced Stacker PLUS. The individual frames are animated in the upper left while each of the stack results are shown in different windows.
Note how things like the airplane trail and the sky brightness change differently for each stacking mode.
Also, the images on the right half are using the "Foreground Masking" option. The foreground being used is from the single frame in which the tree is lit. That foreground frame coresponds to the "flash" you see in the original.
The timelapse/compositing was created using Photoshop CC while all of the frames were created using Advanced Stacker PLUS version 14.
